The success of “Mad Men” has paved the way for at least two new, look-alike series this fall — ABC’s sexy stewardess-centered “Pan Am” and NBC’s recreation of the cave man days of the sexual revolution, “The Playboy Club.”

The Cold War era is making a comeback.

The two new series involve “a time period and concepts that elicit wish fulfillment and excitement,” says Jen Grisanti, a former TV exec and author of “Story Line: Finding Gold in Your Life Story.”
